Lockable device validation for information handling systems

ABSTRACT

Systems and procedures are provided for validating an IHS (Information Handling System) as operating using only factory-provisioned lockable devices. During factory provisioning of the IHS, a signed inventory certificate is uploaded to the IHS that includes an inventory of factory-provisioned lockable devices and also includes encrypted code(s) for accessing the lockable devices. Upon delivery and initialization of the IHS, the inventory certificate is retrieved by a pre-boot validation process. An inventory of detected lockable devices of the IHS is then collected. The validation process compares the collected inventory of detected lockable devices against the inventory of factory-provisioned lockable devices from the inventory certificate in order to validate the IHS is operating using only factory-provisioned lockable devices. If a lockable device is validated as factory-provisioned, the encrypted code included in the inventory certificate is deciphered using a private key of the customer in order to gain access the lockable device.

FIELD

The present disclosure relates generally to Information Handling Systems (IHSs), and relates more particularly to IHS security.

BACKGROUND

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is Information Handling Systems (IHSs). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in IHSs allow for IHSs to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

Some types of IHSs, such as mobile phones and tablets, are typically manufactured in large quantities and with few variations. For instance, for a particular model of mobile phone or tablet, hundreds of thousands of identical, or nearly identical, devices may be manufactured. Other types of IHSs, such as rack-mounted servers, are manufactured in much smaller quantities and are frequently manufactured and customized according to specifications provided by a specific customer that has contracted for the manufacture and delivery of the server. In such instances, a customer may specify various hardware and/or software customizations that configure the server to support specific functionality. For example, a customer may contract for manufacture and delivery of a server that includes security adaptations that will enable the server to securely process high volumes of financial transactions. In some such security adaptations, a customer may also contract for the installation of specifically identified secured devices in an IHS, such as lockable devices that cannot be accessed without a specific code.

SUMMARY

In various embodiments, methods are provided for validating secure assembly and delivery of an IHS (Information Handling System) for a customer. The methods may include: retrieving an inventory certificate uploaded to the IHS during factory provisioning of the IHS for the customer, wherein the inventory certificate includes an inventory identifying a factory-installed lockable device of the IHS, and wherein the inventory certificate further includes an encrypted code for accessing the lockable device; collecting an inventory of detected lockable devices of the IHS; comparing the collected inventory of detected lockable devices against the inventory from the inventory certificate in order to validate the IHS is operating using only factory-installed lockable devices; and validating that the encrypted code included in the inventory certificate is decipherable using a private key of the customer such that the deciphered code provides access to the lockable device.

In some method embodiments, the code included in the inventory certificate is encrypted during factory provisioning of the IHS using a public key of the customer. In some method embodiments, receiving an updated inventory certificate including an inventory that specifies modifications to the lockable devices that are operable on the IHS; and comparing an updated inventory of detected lockable devices against the inventory from the updated inventory certificate in order to validate the IHS is operating using only factory-installed or factory-provisioned lockable devices. In some method embodiments, the modifications specified in the updated inventory certificate comprise a new lockable device that is being added to the IHS and an encrypted code for accessing the new lockable device. In some method embodiments, the inventory certificate is uploaded to a persistent memory of a remote access controller of the IHS during the factory provisioning of the IHS. In some method embodiments, the access code is generated by the remote access controller of the IHS. In some method embodiments, the lockable device comprises a lockable storage device. In some method embodiments, the deciphered code allows commands to be issued to the lockable storage device. In some method embodiments, the deciphered code allows data stored on the lockable storage device to be deciphered.

In various additional embodiments, IHSs (Information Handling Systems) may include: a plurality of lockable devices; a persistent memory, wherein during factory provisioning of the IHS an inventory certificate is uploaded to the persistent memory, wherein the inventory certificate includes an inventory that identifies the plurality of lockable devices as factory-installed components of the IHS, and wherein the inventory certificate further includes a plurality of encrypted codes for accessing the factory-installed lockable devices; one or more processors; and one or more memory devices coupled to the processors, the memory devices storing computer-readable instructions that, upon execution by the processors, cause the IHS to: retrieve the inventory certificate stored to the persistent memory during factory provisioning of the IHS; collecting an inventory of detected lockable devices of the IHS; compare the collected inventory of detected lockable devices against the inventory from the inventory certificate in order to validate the IHS is operating using only the factory-installed lockable devices; and validate that the encrypted codes included in the inventory certificate are decipherable using one or more private keys of the customer such that the deciphered codes provide access to the lockable devices.

In some IHS embodiments, the code included in the inventory certificate is encrypted during factory provisioning of the IHS using a public key of the customer. In some IHS embodiments, execution of the instructions by the processor further causes the IHS to: receive an updated inventory certificate including an inventory that specifies modifications to the lockable devices that are operable on the IHS; and compare an updated inventory of detected lockable devices against the inventory from the updated inventory certificate in order to validate the IHS is operating using only factory-installed or factory-provisioned lockable devices. In some IHS embodiments, the modifications specified in the updated inventory certificate comprise a new lockable device that is being added to the IHS and an encrypted code for accessing the new lockable device. In some IHS embodiments, the access code is generated by a remote access controller of the IHS. In some IHS embodiments, the lockable devices comprise a lockable storage device.

In various additional embodiments, computer-readable storage devices include instructions stored thereon for validating secure assembly and delivery of an IHS (Information Handling System). Execution of the instructions by one or more processors of the IHS causes a validation process of the IHS to: retrieve an inventory certificate uploaded to the IHS during factory provisioning of the IHS for the customer, wherein the inventory certificate includes an inventory identifying a factory-installed lockable device of the IHS, and wherein the inventory certificate further includes an encrypted code for accessing the lockable device; collect an inventory of detected lockable devices of the IHS; compare the collected inventory of detected lockable devices against the inventory from the inventory certificate in order to validate the IHS is operating using only factory-installed lockable devices; and validate that the encrypted code included in the inventory certificate is decipherable using a private key of the customer such that the deciphered code provides access to the lockable device.

In some storage device embodiments, the code included in the inventory certificate is encrypted during factory provisioning of the IHS using a public key of the customer. In some storage device embodiments, the lockable device comprises a lockable storage device. In some storage device embodiments, the deciphered code allows commands to be issued to the lockable storage device. In some storage device embodiments, the deciphered code allows data stored on the lockable storage device to be deciphered.

DETAILED DESCRIPTION

FIG. 1 is a block diagram illustrating certain components of a chassis 100 comprising one or more compute sleds 105 a-n and one or more storage sleds 115 a-n that may be configured to implement the systems and methods described herein for validating that the chassis 100 includes one or more specific factory-installed lockable storage devices. Embodiments of chassis 100 may include a wide variety of different hardware configurations. Such variations in hardware configuration may result from chassis 100 being factory assembled to include components specified by a customer that has contracted for manufacture and delivery of chassis 100. As described in additional detail below, chassis 100 may include capabilities that allow a customer to validate that, upon delivery and initialization, chassis 100 includes a lockable storage device that is factory-installed and that requires a customer’s cryptographic key in order to access the storage device.

Chassis 100 may include one or more bays that each receive an individual sled (that may be additionally or alternatively referred to as a tray, blade, and/or node), such as compute sleds 105 a-n and storage sleds 115 a-n. Chassis 100 may support a variety of different numbers (e.g., 4, 8, 16, 32), sizes (e.g., single-width, double-width) and physical configurations of bays. Other embodiments may include additional types of sleds that provide various types of storage and/or processing capabilities. Other types of sleds may provide power management and networking functions. Sleds may be individually installed and removed from the chassis 100, thus allowing the computing and storage capabilities of a chassis to be reconfigured by swapping the sleds with different types of sleds, in many cases without affecting the operations of the other sleds installed in the chassis 100.

Multiple chassis 100 may be housed within a rack. Data centers may utilize large numbers of racks, with various different types of chassis installed in the various configurations of racks. The modular architecture provided by the sleds, chassis and rack allow for certain resources, such as cooling, power and network bandwidth, to be shared by the compute sleds 105 a-n and storage sleds 115 a-n, thus providing efficiency improvements and supporting greater computational loads.

Chassis 100 may be installed within a rack structure that provides all or part of the cooling utilized by chassis 100. For airflow cooling, a rack may include one or more banks of cooling fans that may be operated to ventilate heated air from within the chassis 100 that is housed within the rack. The chassis 100 may alternatively or additionally include one or more cooling fans 130 that may be similarly operated to ventilate heated air from within the sleds 105 a-n, 115 a-n installed within the chassis. A rack and a chassis 100 installed within the rack may utilize various configurations and combinations of cooling fans to cool the sleds 105 a-n, 115 a-n and other components housed within chassis 100.

The sleds 105 a-n, 115 a-n may be individually coupled to chassis 100 via connectors that correspond to the bays provided by the chassis 100 and that physically and electrically couple an individual sled to a backplane 160. Chassis backplane 160 may be a printed circuit board that includes electrical traces and connectors that are configured to route signals between the various components of chassis 100 that are connected to the backplane 160. In various embodiments, backplane 160 may include various additional components, such as cables, wires, midplanes, backplanes, connectors, expansion slots, and multiplexers. In certain embodiments, backplane 160 may be a motherboard that includes various electronic components installed thereon. Such components installed on a motherboard backplane 160 may include components that implement all or part of the functions described with regard to the SAS (Serial Attached SCSI) expander 150, I/O controllers 145, network controller 140 and power supply unit 135. In some embodiments, a backplane 160 may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of the backplane 160 by its manufacturer. As described below, embodiments may support validation of backplane 160 as being the same backplane that was installed at the factory during the manufacture of chassis 100.

In certain embodiments, a compute sled 105 a-n may be an IHS such as described with regard to IHS 200 of FIG. 2 . A compute sled 105 a-n may provide computational processing resources that may include one or more processors 170 a-n and may be used to support a variety of e-commerce, multimedia, business and scientific computing applications, such as services provided via a cloud implementation. Compute sleds 105 a-n are typically configured with hardware and software that provide leading-edge computational capabilities. Accordingly, services provided using such computing capabilities are typically provided as high-availability systems that operate with minimum downtime. As described in additional detail with regard to FIG. 2 , compute sleds 105 a-n may be configured for general-purpose computing or may be optimized for specific computing tasks.

As illustrated, each compute sled 105 a-n includes a remote access controller (RAC) 110 a-n. As described in additional detail with regard to FIG. 2 , remote access controller 110 a-n provides capabilities for remote monitoring and management of compute sled 105 a-n. In support of these monitoring and management functions, remote access controllers 110 a-n may utilize both in-band and sideband (i.e., out-of-band) communications with various components of a compute sled 105 a-n and chassis 100. Remote access controllers 110 a-n may collect various types of sensor data, such as collecting temperature sensor readings that are used in support of airflow cooling of the chassis 100 and the sleds 105 a-n, 115 a-n. In addition, each remote access controller 110 a-n may implement various monitoring and administrative functions related to compute sleds 105 a-n that utilize sideband bus connections with various internal components of the respective compute sleds 105 a-n.

In some embodiments, each compute sled 105 a-n installed in chassis 100 may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of a respective compute sled 105 a-n by its manufacturer. As described below, embodiments support validation of each compute sled 105 a-n as being a compute sled that was installed at the factory during the manufacture of chassis 100. Also as described below, during a provisioning phase of the factory assembly of chassis 100, a signed certificate that specifies hardware components of chassis 100 that were installed during its manufacture may be stored in a non-volatile memory accessed by a remote access controller 110 a-n of a compute sled 105 a-n. Using this signed inventory certificate, a customer may validate that the hardware components of chassis 100 and/or compute sled 105 a-n are the same components that were installed at the factory during its manufacture. As described in additional detail below, embodiments also allow a customer to validate that chassis 100 includes a specific factory-installed lockable storage device.

Each of the compute sleds 105 a-n may include a storage controller 135 a-n that may be utilized to access storage drives that are accessible via chassis 100. Some of the individual storage controllers 135 a-n may provide support for RAID (Redundant Array of Independent Disks) configurations of logical and physical storage drives, such as storage drives provided by storage sleds 115 a-n, some or all of which may be lockable storage drives, as described herein. In some embodiments, some or all of the individual storage controllers 135 a-n may be HBAs (Host Bus Adapters) that provide more limited capabilities in accessing physical storage drives provided via storage sleds 115 a-n and/or via SAS expander 150.

In addition to the data storage capabilities provided by storage sleds 115 a-n, chassis 100 may provide access to other storage resources that may be installed components of chassis 100 and/or may be installed elsewhere within a rack housing the chassis 100, such as within a storage blade. In certain scenarios, such storage resources 155 may be accessed via a SAS expander 150 that is coupled to the backplane 160 of the chassis 100. The SAS expander 150 may support connections to a number of JBOD (Just a Bunch Of Disks) storage drives 155, some or all of which may be lockable storage drives, that may be configured and managed individually and without implementing data redundancy across the various drives 155. The additional storage resources 155 may also be at various other locations within a datacenter in which chassis 100 is installed. Such additional storage resources 155 may also be remotely located. In some embodiments, a SAS expander 150 and storage drive 155 may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of the SAS expander 150 or storage drive 155 by its respective manufacturer. In instances where SAS expander 150 and storage drives 155 are factory installed, as described below, embodiments may support validation of SAS expander 150 and storage drives 155 as being the same SAS expander and storage drives that were installed at the factory during the manufacture of chassis 100.

As illustrated, chassis 100 also includes one or more storage sleds 115 a-n that are coupled to the backplane 160 and installed within one or more bays of chassis 200 in a similar manner to compute sleds 105 a-n. Each of the individual storage sleds 115 a-n may include various different numbers and types of storage devices, some or all of which may be lockable storage drives. For instance, storage sleds 115 a-n may include SAS (Serial Attached SCSI) magnetic disk drives, SATA (Serial Advanced Technology Attachment) magnetic disk drives, solid-state drives (SSDs) and other types of storage drives in various combinations. The storage sleds 115 a-n may be utilized in various storage configurations by the compute sleds 105 a-n that are coupled to chassis 100. As illustrated, each storage sled 115 a-n includes a remote access controller (RAC) 120 a-n provides capabilities for remote monitoring and management of respective storage sleds 115 a-n. In some embodiments, each storage sled 115 a-n may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of the respective storage sled 115 a-n by its manufacturer. As described below, embodiments support validation of each storage sled 115 a-n as being a storage sled that was installed at the factory during the manufacture of chassis 100. Also as described below, embodiments support validation that any lockable storage device included in the storage sleds 115 a-n is a factory-installed device that can only be accessed using the cryptographic key of the customer for which chassis 100 has been factory provisioned.

As illustrated, the chassis 100 of FIG. 1 includes a network controller 140 that provides network access to the sleds 105 a-n, 115 a-n installed within the chassis. Network controller 140 may include various switches, adapters, controllers and couplings used to connect chassis 100 to a network, either directly or via additional networking components and connections provided via a rack in which chassis 100 is installed. In some embodiments, a network controller 140 may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of the network controller 140 by its manufacturer. As described below, embodiments support validation of network controller 140 as being the same network controller that was installed at the factory during the manufacture of chassis 100.

Chassis 100 may similarly include a power supply unit 135 that provides the components of the chassis with various levels of DC power from an AC power source or from power delivered via a power system provided by a rack within which chassis 100 may be installed. In certain embodiments, power supply unit 135 may be implemented within a sled that may provide chassis 100 with redundant, hot-swappable power supply units. In some embodiments, a power supply unit 135 may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of the power supply unit 135 by its manufacturer. As described below, embodiments support validation of power supply unit 135 as being the same power supply unit that was installed at the factory during the manufacture of chassis 100.

Chassis 100 may also include various I/O controllers 145 that may support various I/O ports 165, such as USB ports that may be used to support keyboard and mouse inputs and/or video display capabilities. Such I/O controllers 145 may be utilized by the chassis management controller 125 to support various KVM (Keyboard, Video and Mouse) 125 a capabilities that provide administrators with the ability to interface with the chassis 100. In some embodiments, each I/O controller 145 may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of the respective I/O controller 140 by its manufacturer. As described below, embodiments support validation of I/O controllers 140 as being the same I/O controllers that were installed at the factory during the manufacture of chassis 100.

The chassis management controller 125 may also include a storage module 125 c that provides capabilities for managing and configuring certain aspects of the storage devices of chassis 100, such as the storage devices provided within storage sleds 115 a-n and within the JBOD 155. In some embodiments, a chassis management controller 125 may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of the chassis management controller 125 by its manufacturer. As described below, embodiments support validation of chassis management controller 125 as being the same chassis management controller that was installed at the factory during the manufacture of chassis 100.

In addition to providing support for KVM 125 a capabilities for administering chassis 100, chassis management controller 125 may support various additional functions for sharing the infrastructure resources of chassis 100. In some scenarios, chassis management controller 125 may implement tools for managing the power 135, network bandwidth 140 and airflow cooling 130 that are available via the chassis 100. As described, the airflow cooling 130 utilized by chassis 100 may include an airflow cooling system that is provided by a rack in which the chassis 100 may be installed and managed by a cooling module 125 b of the chassis management controller 125.

It should be appreciated that although the embodiments described herein may describe an IHS that is a compute sled or similar computing component that may be deployed within the bays of a chassis, other embodiments may be utilized with other types of IHSs, such as servers, desktops and laptops, that may also support validation of the secure assembly and delivery of the IHS 200, and validation of a specific factory-installed lockable storage device. In the illustrative embodiment of FIG. 2 , IHS 200 may be a computing component, such as compute sled 105 a-n or other type of server, such as an 1RU server installed within a 2RU chassis, that is configured to share infrastructure resources provided by a chassis 100.

The IHS 200 of FIG. 2 may be a compute sled, such as compute sleds 105 a-n of FIG. 1 , that may be installed within a chassis, that may in turn be installed within a rack. Installed in this manner, IHS 200 may utilize shared power, network and cooling resources provided by the chassis and/or rack. Embodiments of IHS 200 may include a wide variety of different hardware configurations. Such variations in hardware configurations may result from IHS 200 being factory assembled to include components specified by a customer that has contracted for manufacture and delivery of IHS 200. As described in additional detail below, IHS 200 may include capabilities that allow a customer to validate that the hardware components of IHS 200 are the same hardware components that were installed at the factory during its manufacture. Also as described in additional detail below, embodiments further allow a customer to validate that IHS 200 includes one or more specific factory-installed lockable storage devices 240 a-n.

In certain embodiments, one or all of processor(s) 205 may be graphics processing units (GPUs) in scenarios where IHS 200 has been configured to support functions such as multimedia services and graphics applications. In some embodiments, each of the processors 205 may be uniquely identified based on a code or other identifier that may be permanently encoded in a respective processor 205 by its manufacturer. As described below, embodiments support validation of processors 205 as being the same processors that were installed at the factory during the manufacture of IHS 200.

As illustrated, processor(s) 205 includes an integrated memory controller 205 a that may be implemented directly within the circuitry of the processor 205, or the memory controller 205 a may be a separate integrated circuit that is located on the same die as the processor 205. The memory controller 205 a may be configured to manage the transfer of data to and from the system memory 210 of the IHS 205 via a high-speed memory interface 205 b. The system memory 210 is coupled to processor(s) 205 via a memory bus 205 b that provides the processor(s) 205 with high-speed memory used in the execution of computer program instructions by the processor(s) 205. Accordingly, system memory 210 may include memory components, such as static RAM (SRAM), dynamic RAM (DRAM), NAND Flash memory, suitable for supporting high-speed memory operations by the processor(s) 205. In certain embodiments, system memory 210 may combine both persistent, non-volatile memory and volatile memory.

In certain embodiments, the system memory 210 may be comprised of multiple removable memory modules. The system memory 210 of the illustrated embodiment includes removable memory modules 210 a-n. Each of the removable memory modules 210 a-n may correspond to a printed circuit board memory socket that receives a removable memory module 210 a-n, such as a DIMM (Dual In-line Memory Module), that can be coupled to the socket and then decoupled from the socket as needed, such as to upgrade memory capabilities or to replace faulty memory modules. Other embodiments of IHS system memory 210 may be configured with memory socket interfaces that correspond to different types of removable memory module form factors, such as a Dual In-line Package (DIP) memory, a Single In-line Pin Package (SIPP) memory, a Single In-line Memory Module (SIMM), and/or a Ball Grid Array (BGA) memory. In some embodiments, each of the memory modules 210 a-n may be uniquely identified based on a code or other identifier that may be permanently encoded in a respective memory module 210 a-n by its manufacturer. As described below, embodiments support validation of memory modules 210 a-n as being the same memory modules that were installed at the factory during the manufacture of IHS 200

IHS 200 may utilize a chipset that may be implemented by integrated circuits that are connected to each processor 205. All or portions of the chipset may be implemented directly within the integrated circuitry of an individual processor 205. The chipset may provide the processor(s) 205 with access to a variety of resources accessible via one or more in-band buses 215. Various embodiments may utilize any number of buses to provide the illustrated pathways served by in-band bus 215. In certain embodiments, in-band bus 215 may include a PCIe (PCI Express) switch fabric that is accessed via a PCIe root complex.

IHS 200 may also include one or more I/O ports 250, such as USB ports, PCIe ports, TPM (Trusted Platform Module) connection ports, HDMI ports, audio ports, docking ports, network ports, Fibre Channel ports and other storage drive ports. Such I/O ports 250 may be externally accessible or may be internal ports that are accessed by opening the enclosure of the IHS 200. Through couplings made to these I/O ports 250, users may couple the IHS 200 directly to other IHSs, storage resources, external networks and a vast variety of peripheral components.

As illustrated, IHS 200 may include one or more FPGA (Field-Programmable Gate Array) cards 220. Each of the FPGA card 220 supported by IHS 200 may include various processing and memory resources, in addition to an FPGA logic unit that may include circuits that can be reconfigured after deployment of IHS 200 through programming functions supported by the FPGA card 220. Through such reprogramming of such logic units, each individual FGPA card 220 may be optimized to perform specific processing tasks, such as specific signal processing, security, data mining, and artificial intelligence functions, and/or to support specific hardware coupled to IHS 200. In some embodiments, a single FPGA card 220 may include multiple FPGA logic units, each of which may be separately programmed to implement different computing operations, such as in computing different operations that are being offloaded from processor 205. The FPGA card 220 may also include a management controller 220 a that may support interoperation with the remote access controller 255 via a sideband device management bus 275 a. In some embodiments, each of the FPGA cards 220 installed in IHS 200 may be uniquely identified based on a code or other identifier that may be permanently encoded in the FPGA card 220 by its manufacturer. As described below, embodiments support validation of FPGA card 220 as being the same FPGA card that was installed at the factory during the manufacture of IHS 200.

Processor(s) 205 may also be coupled to a network controller 225 via in-band bus 215, such as provided by a Network Interface Controller (NIC) that allows the IHS 200 to communicate via an external network, such as the Internet or a LAN. In some embodiments, network controller 225 may be a replaceable expansion card or adapter that is coupled to a motherboard connector of IHS 200. In some embodiments, network controller 225 may be an integrated component of IHS 200. In some embodiments, network controller 225 may be uniquely identified based on a code or other identifier, such as a MAC address, that may be permanently encoded in a non-volatile memory of network controller 225 by its manufacturer. As described below, embodiments support validation of network controller 225 as being the same network controller that was installed at the factory during the manufacture of IHS 200.

IHS 200 may include one or more storage controllers 230 that may be utilized to access storage drives 240 a-n that are accessible via the chassis in which IHS 100 is installed. Storage controller 230 may provide support for RAID (Redundant Array of Independent Disks) configurations of logical and physical storage drives 240 a-n. In some embodiments, storage controller 230 may be an HBA (Host Bus Adapter) that provides more limited capabilities in accessing physical storage drives 240 a-n. In some embodiments, storage drives 240 a-n may be replaceable, hot-swappable storage devices that are installed within bays provided by the chassis in which IHS 200 is installed. In embodiments where storage drives 240 a-n are hot-swappable devices that are received by bays of chassis, the storage drives 240 a-n may be coupled to IHS 200 via couplings between the bays of the chassis and a midplane of IHS 200. In some embodiments, storage drives 240 a-n may also be accessed by other IHSs that are also installed within the same chassis as IHS 100.

As illustrated, IHS 100 may include one or more lockable storage drives 240 an. IHS 100 may also include various additional storage drives that are not lockable in the manner described herein. In some embodiments, each of the lockable storage drives 240 a-n is a storage device, or collection of storage devices, that require a customer’s cryptographic key in order to unlock or otherwise access. As described in additional detail below, during factory provisioning of an IHS, a code that is required to operate each individual lockable storage drive 240 a-n may be encrypted using a public cryptographic key provided by the customer and included in the generated inventory certificate that is stored to a persistent memory of the IHS 200. Upon delivery of IHS 200, the customer may utilize the inventory certificate information to validate the lockable storage drives 240 a-n as being factory installed, and once a lockable storage drive has been validated, may utilize their private cryptographic key in order to gain access to the code required to operate each of the storage drives. In some embodiments, the code for a lockable storage device provides access to the storage device such that no operations, or minimal operations, are supported by the lockable storage device without a requester providing the access code. For instance, a lockable storage device may support no commands or very limited commands for requestors that do not present the correct access code. In some embodiments, the code for a lockable storage device provides the ability to decrypt the data that is stored by the lockable storage device. In various embodiments, each of the lockable storage drives 240 a-n may be SAS (Serial Attached SCSI) magnetic disk drives, SATA (Serial Advanced Technology Attachment) magnetic disk drives, solid-state drives (SSDs) and other types of storage drives.

For sake of clarity, embodiments describe validation and accessing lockable storage devices. However, additional embodiments may operate to validate and access other types of devices of the IHS that may be similarly lockable. For instance, these other types of lockable devices may similarly support no commands or limited commands to requestors that do not present a specific access code. In other instances, these other types of lockable devices may store encrypted data that cannot be deciphered without the correct access code for a lockable device. For instance, an FPGA card 220 may support one or more APIs for operation of FPGA capabilities, but some or all of the commands supported by the API may only be invoked with an access code for the FPGA. Some or all of the capabilities of a network controller 225, storage controller 230 or other components of IHS 200 may be similarly unlocked using a code that is encrypted and included in an inventory certificate as described herein.

A variety of additional components may be coupled to processor(s) 205 via in-band bus 215. For instance, processor(s) 205 may also be coupled to a power management unit 260 that may interface with the power system unit 135 of the chassis 100 in which an IHS, such as a compute sled, may be installed. In certain embodiments, a graphics processor 235 may be comprised within one or more video or graphics cards, or an embedded controller, installed as components of the IHS 200. In certain embodiments, graphics processor 235 may be an integrated component of the remote access controller 255 and may be utilized to support the display of diagnostic and administrative interfaces related to IHS 200 via display devices that are coupled, either directly or remotely, to remote access controller 255. In some embodiments, components such as power management unit 260 and graphics processor 235 may also be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of these components by their respective manufacturer. As described below, embodiments support validation of these components as being components that were installed at the factory during the manufacture of IHS 200.

In certain embodiments, IHS 200 may operate using a BIOS (Basic Input/Output System) that may be stored in a non-volatile memory accessible by the processor(s) 205. The BIOS may provide an abstraction layer by which the operating system of the IHS 200 interfaces with the hardware components of the IHS. Upon powering or restarting IHS 200, processor(s) 205 may utilize BIOS instructions to initialize and test hardware components coupled to the IHS, including both components permanently installed as components of the motherboard of IHS 200 and removable components installed within various expansion slots supported by the IHS 200. The BIOS instructions may also load an operating system for use by the IHS 200. In certain embodiments, IHS 200 may utilize Unified Extensible Firmware Interface (UEFI) in addition to or instead of a BIOS. In certain embodiments, the functions provided by a BIOS may be implemented, in full or in part, by the remote access controller 255. As described in additional detail below, in some embodiments, BIOS may be configured to identify hardware components that are detected as being currently installed in IHS 200. In such instances, the BIOS may support queries that provide the described unique identifiers that have been associated with each of these detected hardware components by their respective manufacturers.

In some embodiments, IHS 200 may include a TPM (Trusted Platform Module) that may include various registers, such as platform configuration registers, and a secure storage, such as an NVRAM (Non-Volatile Random-Access Memory). The TPM may also include a cryptographic processor that supports various cryptographic capabilities. In IHS embodiments that include a TPM, a pre-boot process implemented by the TPM may utilize its cryptographic capabilities to calculate hash values that are based on software and/or firmware instructions utilized by certain core components of IHS, such as the BIOS and boot loader of IHS 200. These calculated hash values may then be compared against reference hash values that were previously stored in a secure non-volatile memory of the IHS, such as during factory provisioning of IHS 200. In this manner, a TPM may establish a root of trust that includes core components of IHS 200 that are validated as operating using instructions that originate from a trusted source.

As described, IHS 200 may include a remote access controller 255 that supports remote management of IHS 200 and of various internal components of IHS 200. In certain embodiments, remote access controller 255 may operate from a different power plane from the processors 205 and other components of IHS 200, thus allowing the remote access controller 255 to operate, and management tasks to proceed, while the processing cores of IHS 200 are powered off. As described, various functions provided by the BIOS, including launching the operating system of the IHS 200, may be implemented by the remote access controller 255. In some embodiments, the remote access controller 255 may perform various functions to verify the integrity of the IHS 200 and its hardware components prior to initialization of the operating system of IHS 200 (i.e., in a bare-metal state). In some embodiments, certain operations of the remote access controller 225, such as the described inventory certificate generation and validation operations, may operate using validated instructions, and thus within the root of trust of IHS 200.

In some embodiments, remote access controller 255 may be uniquely identified based on a code or other identifier that may be permanently encoded in a non-volatile memory of the remote access controller 255 by its manufacturer. As described below, embodiments support validation of remote access controller 255 as being the same controller that was installed at the factory during the manufacture of IHS 200. In scenarios where remote access controller 255 of IHS 200 is replaced, embodiments support validation that a replacement remote access controller installed by a customer in IHS 200 is the same remote access controller that was supplied to the customer. Also as described below, during a provisioning phase of the factory assembly of IHS 200, a signed certificate that specifies factory installed hardware components of IHS 200 that were installed during manufacture of the IHS 200 may be stored in a non-volatile memory that is accessed by remote access controller 255. Using this signed inventory certificate stored by the remote access controller 255, a customer may validate that the detected hardware components of IHS 200 are the same hardware components that were installed at the factory during manufacture of IHS 200. Also as described below, embodiments further allow use of this signed inventory certificate stored by the remote access controller 255 to validate that IHS 200 includes one or more specific factory-installed lockable storage devices 240 a-n.

In support of the capabilities for validating the detected hardware components of IHS 200 against the inventory information that is specified in a signed inventory certificate, remote access controller 255 may support various cryptographic capabilities. For instance, remote access controller 255 may include capabilities for key generation such that remote access controller may generate keypairs that include a public key and a corresponding private key. As described in additional detail below, using generated keypairs, remote access controller 255 may digitally sign inventory information collected during the factory assembly of IHS 200 such that the integrity of this signed inventory information may be validated at a later time using the public key by a customer that has purchased IHS 200. Using these cryptographic capabilities of the remote access controller, the factory installed inventory information that is included in an inventory certificate may be anchored to a specific remote access controller 255, since the keypair used to sign the inventory information is signed using the private key that is generated and maintained by the remote access controller 255.

In some embodiment, the cryptographic capabilities of remote access controller 255 may also include safeguards for encrypting any private keys that are generated by the remote access controller and further anchoring them to components within the root of trust of IHS 200. For instance, a remote access controller 255 may include capabilities for accessing hardware root key (HRK) capabilities of IHS 200, such as for encrypting the private key of the keypair generated by the remote access controller. In some embodiments, the HRK may include a root key that is programmed into a fuse bank, or other immutable memory such as one-time programmable registers, during factory provisioning of IHS 200. The root key may be provided by a factory certificate authority, such as described below. By encrypting a private key using the hardware root key of IHS 200, the hardware inventory information that is signed using this private key is further anchored to the root of trust of IHS 200. If a root of trust cannot be established through validation of the remote access controller cryptographic functions that are used to access the hardware root key, the private key used to sign inventory information cannot be retrieved. In some embodiments, the private key that is encrypted by the remote access controller using the HRK may be stored to a replay protected memory block (RPMB) that is accessed using security protocols that require all commands accessing the RPMB to be digitally signed using a symmetric key and that include a nonce or other such value that prevents use of commands in replay attacks. Stored to an RPMG, the encrypted private key can only be retrieved by a component within the root of trust of IHS 200, such as the remote access controller 255.. In some embodiments, the remote access controller 255 may rely on certain cryptographic capabilities of a TPM, such as in generating keypairs, calculating cryptographic signatures (e.g., hashes) and/or providing a persistent and secure memory for storage of the keypair used by the hardware validation procedures described in more detail below.

Utilizing its cryptographic capabilities, a remote access controller 255 may generate CSRs (certificate signing requests) that are usable in requesting an identity certificate, such as an X.509 certificate, from a certificate authority. A CSR generated by remote access controller 255 may be submitted to a certificate authority that may attest to ownership by the remote access controller 255 of the private key that corresponds to a public key included in the CSR. As described in additional detail below, CSRs generated by a remote access controller 255 may include an inventory of the factory-installed hardware components of the IHS 200, where the inventory information is signed by the remote access controller 255. This signed inventory information included in the inventory certificate may then be used to validate the detected hardware of the IHS 200 as genuine factory-installed components.

Remote access controller 255 may include a service processor 255 a, or specialized microcontroller, that operates management software that supports remote monitoring and administration of IHS 200. Remote access controller 255 may be installed on the motherboard of IHS 200 or may be coupled to IHS 200 via an expansion slot provided by the motherboard. In support of remote monitoring functions, network adapter 225 c may support connections with remote access controller 255 using wired and/or wireless network connections via a variety of network technologies. As a non-limiting example of a remote access controller, the integrated Dell Remote Access Controller (iDRAC) from Dell® is embedded within Dell PowerEdge™ servers and provides functionality that helps information technology (IT) administrators deploy, update, monitor, and maintain servers remotely.

In some embodiments, remote access controller 255 may support monitoring and administration of various managed devices 220, 225, 230, 280 of an IHS via a sideband bus interface. For instance, messages utilized in device management may be transmitted using I2C sideband bus connections 275 a-d that may be individually established with each of the respective managed devices 220, 225, 230, 280 through the operation of an I2C multiplexer 255 d of the remote access controller. As illustrated, certain of the managed devices of IHS 200, such as non-standard hardware 220, network controller 225 and storage controller 230, are coupled to the IHS processor(s) 205 via an in-line bus 215, such as a PCIe root complex, that is separate from the I2C sideband bus connections 275 a-d used for device management. The management functions of the remote access controller 255 may utilize information collected by various managed sensors 280 located within the IHS. For instance, temperature data collected by sensors 280 may be utilized by the remote access controller 255 in support of closed-loop airflow cooling of the IHS 200.

In certain embodiments, the service processor 255 a of remote access controller 255 may rely on an I2C co-processor 255 b to implement sideband I2C communications between the remote access controller 255 and managed components 220, 225, 230, 280 of the IHS. The I2C co-processor 255 b may be a specialized co-processor or micro-controller that is configured to interface via a sideband I2C bus interface with the managed hardware components 220, 225, 230, 280 of IHS. In some embodiments, the I2C co-processor 255 b may be an integrated component of the service processor 255 a, such as a peripheral system-on-chip feature that may be provided by the service processor 255 a. Each I2C bus 275 a-d is illustrated as single line in FIG. 2 . However, each I2C bus 275 a-d may be comprised of a clock line and data line that couple the remote access controller 255 to I2C endpoints 220 a, 225 a, 230 a, 280 a which may be referred to as modular field replaceable units (FRUs).

As illustrated, the I2C co-processor 255 b may interface with the individual managed devices 220, 225, 230, 280 via individual sideband I2C buses 275 a-d selected through the operation of an I2C multiplexer 255 d. Via switching operations by the I2C multiplexer 255 d, a sideband bus connection 275 a-d may be established by a direct coupling between the I2C co-processor 255 b and an individual managed device 220, 225, 230, 280. In providing sideband management capabilities, the I2C co-processor 255 b may each interoperate with corresponding endpoint I2C controllers 220 a, 225 a, 230 a, 280 a that implement the I2C communications of the respective managed devices 220, 225, 230. The endpoint I2C controllers 220 a, 225 a, 230 a, 280 a may be implemented as a dedicated microcontroller for communicating sideband I2C messages with the remote access controller 255, or endpoint I2C controllers 220 a, 225 a, 230 a, 280 a may be integrated SoC functions of a processor of the respective managed device endpoints 220, 225, 230, 280.

In various embodiments, an IHS 200 does not include each of the components shown in FIG. 2 . In various embodiments, an IHS 200 may include various additional components in addition to those that are shown in FIG. 2 . Furthermore, some components that are represented as separate components in FIG. 2 may in certain embodiments instead be integrated with other components. For example, in certain embodiments, all or a portion of the functionality provided by the illustrated components may instead be provided by components integrated into the one or more processor(s) 205 as a systems-on-a-chip.

FIG. 3 is a swim lane diagram illustrating certain responsibilities of components of a system configured according to certain embodiments for factory provisioning of an IHS for validating that, once deployed, the IHS includes one or more specific factory-installed lockable storage devices. FIG. 4 is a flowchart describing certain steps of a method, according to some embodiments, for assembly and factory provisioning of an IHS for validating that, once deployed, the IHS includes one or more specific factory-installed lockable storage devices. Some embodiments of the method of FIG. 4 may begin, at block 405, with the factory assembly of an IHS, such as the assembly of a server described with regard to FIGS. 1 and 2 . In some instances, an IHS may be manufactured using a factory process that includes multiple phases of assembly, validation and provisioning that must be completed before the IHS is supplied to a customer. As described, an IHS such as a server may be purpose-built for a particular customer such that the server is assembled and provisioned according to specifications provided by the customer. The initial factory assembly of such server IHSs may include the selection of a chassis and the fastening of various hardware components to the selected chassis. Such a factory assembly process may include generating a manifest that tracks the individual hardware components that are installed in an IHS.

As described above, the installed hardware components may include standard components and may also include specialized components that have been requested by a specific customer that has contracted for the assembly and delivery of an IHS. For instance, as described with regard to FIG. 2 , an IHS may be factory assembled to include one or more lockable storage devices, where each of these storage devices may be separately locked using an access code that must be presented to the storage device in order to gain access to the device. Such storage devices remain locked to any attempts to access the device that do not present the correct access code for that storage device. In some embodiments, instructions for assembly and provisioning of an IHS for a particular customer may specify a particular lockable storage drive, or a type of lockable storage device, for installation in the IHS. Instructions provided by a customer may also include a public key to be used in securing the access codes for one or more of the lockable storage devices to be installed in the IHS. In some embodiments, along with providing the public key for encrypting the access code for a lockable storage device that is factory installed in an IHS, a customer may also provide the access code for a lockable storage device. In some embodiments, this access code for a lockable storage device may instead be generated during the factory provisioning process, such as by the remote access controller 310 of the IHS. In some embodiments, this access code for a lockable storage device may be retrieved from the storage device itself by the remote access controller 310. As will other described hardware components, the lockable storage devices may be specified within the manifest that tracks the hardware components that are installed in the IHS during its factory assembly.

Once the assembly of an IHS has been completed, the IHS may be subjected to manual and automated inspections that confirm the IHS has been properly assembled and does not include any defects. After confirming an IHS has been assembled without any manufacturing defects, at block 410, factory provisioning of the IHS may be initiated. In some instances, the provisioning of an IHS at the factory may include various stages that may include stages for loading of firmware, configuring hardware components, and installing an operating system and other software. As indicated in FIG. 3 , various aspects of this factory provisioning process may be conducted using a factory provisioning application, where this factory provisioning application may run on one or more servers and may interface with an IHS that is being provisioned once a requisite amount of firmware and software has been installed to the IHS.

As described, a manifest of the individual hardware components that are installed in an IHS may be generated during assembly of the IHS. Such a manifest may be a file that includes an entry for each component installed to an IHS, where the entry may specify various characteristics of the component, such as model numbers and installation locations, and may also specify any unique identifiers associated with the component, such as a MAC address or a serial number. As described, in some embodiments, the manifest may specify one or more lockable storage devices installed in the IHS, where these manifest entries may specify a unique identifier, such as a serial number, that identifies each lockable storage device. As described above, in some embodiments, other devices of an IHS other than or in addition to storage devices may be lockable and thus identified as such in a manifest.

At block 415, a manifest including a hardware inventory that is generated during assembly of an IHS is provided to the factory provisioning application that is used to provision the assembled IHS. In scenarios where the factory provisioning application identifies lockable storage devices in the manifest of installed components of the IHS, the factory provisioning application may solicit additional information for the customer that has contracted for the IHS. For instance, the customer for which the IHS is being manufactured may provide the factory provisioning application with one or more public keys, where each of these customer-provided public keys are for use in protecting the access codes for one or more of the lockable storage devices that are installed in the IHS. In some embodiments, the public keys for use with lockable storage drives may be provided during order entry by the customer. In some embodiments, a hardware manifest that specifies a lockable storage device may also specify an access code for accessing that lockable storage device. In some embodiments, the access code for a lockable storage device may be provided by the customer along with a public key for use with that lockable storage device. In some embodiments, the code for the lockable storage device may be generated by the remote access controller of the IHS, such as using the cryptographic capabilities of the remote access controller of FIG. 1 .

At 418, the factory provisioning application utilizes the public key provided for use with a particular lockable storage device to encrypt the code that is required to access that storage device. In some instances, a separate public key will be provided by a customer for the encryption of the access code for each lockable storage device. In other instances, a public key provided by a customer may be used to encrypt the codes for multiple lockable storage devices. Once the codes for the lockable storage devices have been encrypted, the resulting encrypted values are included in the hardware inventory that will included in the inventory certificate that will be generated and stored to the IHS during the factory provisioning. As described in additional detail below, once the IHS has been delivered, the customer can initialize the IHS and validate the lockable storage devices of the IHS are factory installed and then utilize their private cryptographic keys to decipher the encrypted access code that is included in the inventory certificate. Based on the collected hardware inventory information, at block 420, the factory provisioning application may initiate generation of an inventory certificate that may be used to validate that the detected hardware components of the IHS are the same hardware components that were installed during the factory assembly of the IHS and/or to validate that the IHS includes one or more specific factory-installed lockable storage devices.

As described with regard to FIGS. 1 and 2 , an IHS may include a remote access controller that provides capabilities for remote management of an IHS, where these remote management capabilities may include sideband management of various hardware components of an IHS. As indicated in FIG. 3 , the generation of an inventory certificate for a newly assembled IHS may be initiated, at 325, via a request from the factory provisioning application 305 to the remote access controller 310 of the IHS. As described with regard to FIG. 2 , a remote access controller of an IHS may include cryptographic capabilities that operate within the root of trust of the IHS and that include the ability to generate cryptographic keypairs. Utilizing such cryptographic capabilities, at block 425, the remote access controller 310 initiates the generation of an inventory certificate by generating a cryptographic key pair for use in validating the authenticity of inventory information, including an inventory of the lockable storage devices, that is included in an inventory certificate.

At block 430 and at 330, the remote access controller 310 generates a certificate signing request (CSR) for a digital identity certificate, where the request specifies the public key of the key pair generated by the remote access controller and also specifies the factory installed hardware inventory from the manifest that was generated during assembly of the IHS, including an inventory of lockable storage devices and encrypted access codes for the lockable storage devices. In addition, the generated CSR includes a digital signature that is derived through operations of the remote access controller 310 from the inventory of factory installed hardware components, where this inventory may be in the form of the hardware manifest that is generated in the assembly of the IHS and that is provided as an input to the factory provisioning 305. The factory installed and provisioned hardware inventory information included in the CSR may be signed by the remote access controller using the private key from the generated keypair. At block 435 and at 335, the CSR for the requested inventory certificate is transmitted to the factory provisioning application 305 by the remote access controller 310. At block 440, the remote access controller safeguards the private key from the generated key pair. In some embodiments, the remote access controller may encrypt the private key using the hardware root key (HRK) of the IHS and may store the encrypted key to a protected memory, such as the replay protected memory block that is described with regard to FIG. 2 .

Upon receiving the certificate signing request from the remote access controller 310, at block 445 and at 340, the factory provisioning application 305 submits the CSR for signing by a factory certificate authority 315. In some embodiments, the factory provisioning application 305 specifies a factory key to be used by the factory certificate authority 315 in signing the inventory certificate. For instance, the factory provisioning application may include the name of a trusted certificate associated with a factory key as an attribute of the CSR that is transmitted to the factory certificate authority 315. Upon receipt of the CSR, at block 450, the factory certificate authority parses from the CSR: the hardware inventory information, including the inventory of lockable storage devices and encrypted codes for accessing the lockable storage devices, the public key generated by the remote access controller and the information specifying the requested signing key. Based on the information parsed from the CSR, the factory certificate authority generates a digital identity certificate, referred to herein as an inventory certificate, that is associated with the public key provided by the remote access controller and that specifies the factory installed hardware inventory of the IHS, including the inventory of lockable storage devices and encrypted codes for accessing the lockable storage devices.

As indicated in FIG. 3 , at 345, the factory certificate authority 315 submits the generated inventory certificate for signing by a hardware security module 320 that may be a dedicated hardware component of a factory provisioning server that safeguards cryptographic keys and implements cryptographic functions utilized in the factory provisioning process. In some embodiments, the factory certificate authority 315 may also specify a certificate name associated with a signing key that is maintained by the hardware security module 320. At 350, the hardware security module 320 utilizes the private key associated with the specified certificate in order to digitally sign the submitted inventory certificate, which includes the inventory of the factory installed hardware components of the IHS and an inventory of lockable storage devices and encrypted codes for accessing the lockable storage devices. The signed inventory certificate is then returned to the factory certificate authority 315 by the hardware security module 320.

Once the inventory certificate has been signed, at block 460 and at 355, the signed inventory certificate is transmitted from the factory certificate authority 315 to the factory provisioning application 305. As indicated in FIG. 3 at 357, the factory provisioning application 305 may store a copy of the signed inventory certificate. In some instances, the copy may be saved to a data store utilized in providing ongoing support of the IHS once it has been shipped and has been deployed by a customer. At block 465 and at 360, the signed inventory certificate is than loaded to the assembled IHS. As indicated in FIG. 3 , in some embodiments, the signed inventory certificate may be uploaded to a remote access controller 310 of the assembled IHS, such that the signed inventory certificate may be stored to a nonvolatile memory or other persistent storage that is accessible by the remote access controller 310 independent from the operating system of the IHS. In other embodiments, the signed inventory certificate may be uploaded without reliance on the remote access controller to another non-volatile memory of the IHS.

Some embodiments may continue, at 365, with the validation of the signed inventory certificate by the remote access controller 310. Using the public key from the generated keypair, at block 475, the remote access controller decrypts the signature included by the remote access controller in the CSR and confirms that the inventory information included in the signed inventory certificate matches the inventory information that was submitted in the certificate signing request, thus validating the integrity of the generation of the signed inventory certificate. At block 485, the remote access controller confirms that the inventory included in the signed inventory certificate is valid and, at 370, the remote access controller 310 confirms the validity of the inventory certificate with a notification to the factory provisioning application 305. With the generation and validation of the signed inventory certificate completed, additional factory provisioning of the assembled IHS may be completed and, at block 490, the assembled IHS may be shipped from the factory to a customer.

FIG. 5 is a swim lane diagram illustrating certain responsibilities of components of an IHS configured according to certain embodiments for validating that, once delivered and deployed, an IHS includes one or more specific factory-installed lockable storage devices. FIG. 6 is a flowchart describing certain steps of a method, according to some embodiments, for validating an IHS includes one or more specific factory-installed lockable storage devices. Embodiments may begin, at block 605, with the delivery of an IHS to a customer, where the IHS has been assembled and provisioned according to the procedures set forth above. In particular, the delivered IHS has been provisioned at the factory to include a signed inventory certificate that specifies the factory installed hardware components of the IHS and/or lockable storage devices.

Upon receiving an IHS that has been configured in this manner, at block 610, the IHS may be unpacked, assembled and initialized by an administrator. In some instances, an IHS may be ready for immediate deployment by a customer. In other instances, an IHS may require further provisioning by a customer before the IHS is deployed, such as for operation within a particular data center. As such, in various instances, an IHS may be unpacked, assembled and initialized in order to deploy the IHS or to prepare it for further provisioning. At block 615, the IHS has been powered and validation process 510 is initialized within a validation environment 505. In some instances, the validation process 510 may be initialized as part of the initial provisioning of an IHS by a customer. In other instances, the validation process may be initialized upon the customer installing new and/or replacement hardware components in the IHS. In some embodiments, the validation process 510 may run within a pre-boot validation environment 505, such as a PXE (Preboot execution Environment) validation environment. In some embodiments, a PXE validation environment 505 in which a validation process 510 runs may be retrieved from a network location and may thus be executed using the processing and memory capabilities of the IHS. In some embodiments, a PXE validation environment may be retrieved using secure protocols, such as HTTPS, in order to assure the integrity of the validation environment instructions that are utilized. In some embodiments, a pre-boot validation environment 505 in which the validation process 510 runs may include an environment that is executed by the remote access controller of the IHS based on validated firmware instructions. In these embodiments that utilize a pre-boot validation environment 505, the validation of the detected hardware components of the IHS is conducted prior to booting of the operating system of the IHS.

In some embodiments, the validation process may run as part of a diagnostic mode that is supported by an IHS. For instance, an IHS may support a diagnostic mode that may be initiated by a user, or may be initiated automatically in response to detecting various conditions, where the diagnostic mode may support various diagnostic tools, including the described hardware validation procedures. In some embodiments, the diagnostic mode may involve re-booting the IHS to a diagnostic environment, while other embodiments may support diagnostic mode operations that run within the operating system of the IHS. Accordingly, some embodiments may support the described hardware validation procedures as a feature available within the operating system of the IHS. In such embodiments, the operating system may be configured to periodically conduct the described hardware validation procedures, such as on a daily or weekly basis. The operating system may likewise be configured to conduct the hardware validation procedures in response to a detected security notification, such as a notification that a process is attempting to access a protected resource. In some embodiments, the described validation procedures may be implemented remotely, such as via the described HTTPS protocols, where the remote validation procedures may rely both on information retrieved from the IHS via HTTPS and on remote information, such as information maintained by the manufacturer of the IHS or by an entity supporting the administration of the IHS.

At block 620 and as indicated at 535 of FIG. 5 , an inventory certificate validation process 510 is initiated within a validation environment 505 that may include a pre-boot environment, a diagnostic environment or other environment supporting the validation process. In some embodiments, the inventory certificate validation process 510 operates based on validated instructions, such as based on instructions that, when used to calculate a hash value, are confirmed to correspond to a value stored in an immutable memory of the IHS during its factory provisioning. In this manner, the inventory certificate validation process 510 may be added to the root of trust of the IHS. At block 625 and as indicated at 540, the inventory certificate validation process 510 retrieves the signed inventory certificate from the remote access controller 525 or from a persistent memory of the IHS. As described above, the factory provisioning process may include uploading the signed inventory certificate to the remote access controller or to a persistent memory of the IHS.

At this point, the validation process 510 may initiate generation of an inventory of all of the hardware components of the IHS. Accordingly, at block 630 and as indicated at 545, the inventory certificate validation process 510 parses the hardware inventory information from the signed inventory certificate. Using the public key provided in the signed inventory certificate, the inventory validation process 510 may confirm the integrity of the inventory information that is included in the signed inventory certificate. In particular, the validation process 510 may utilize the private key of the keypair generated by the remote access controller 525 during factory provisioning to calculate a signature based on the inventory included in the certificate. If this signature matches the signed inventory signature included in the certificate, the integrity of the inventory included in the certificate is confirmed. If the inventory information included in the certificate does not match the signed inventory included in the certificate, a core validation failure specifying a corrupted inventory certificate may be signaled.

If the validity of the certificate is confirmed, the validation process 510 collects an inventory of the detected hardware components of the IHS. In some instances, this collection of inventory information may be initiated earlier by the inventory certificate validation process, such as during initialization of the IHS and its components. At block 635 and as indicated at 550, the inventory certificate validation process 510 may query the BIOS 515 of the IHS for an inventory of hardware components that have been detected by BIOS 515, including an inventory of lockable storage devices that are recognized by the BIOS. At block 640 and as indicated at 555, the inventory certificate validation process 510 may retrieve additional hardware inventory information from a Trusted Platform Module (TPM) 520 of the IHS, which may also specify lockable storage devices recognized by the TPM. In some instances, the TPM 520 may identify hardware components that are also identified by BIOS 515. However, in some instances, the TPM 520 may identify certain hardware components, such as secure memory modules, that are not identified by BIOS 515.

As described with regard to FIG. 2 , a Trusted Platform Module may serve to establish an initial hardware root of trust in an IHS such that the hardware components within this root of trust operate using validated software instructions. Accordingly, in some embodiments, the inventory validation process 510 may compare identity information for the detected TPM 520 against the TPM identity information that is parsed from the inventory certificate at block 545. In some instances, the detection of any discrepancies between the identity of the TPM specified in the inventory certificate and the identity reported by a detected TPM 520 may result in terminating any further validation procedures.

At block 645 and as indicated at 560, the inventory certificate validation process 510 may retrieve additional hardware inventory information from a remote access controller 525 of the IHS, such as lockable storage devices recognized by the remote access controller 525. As with TPM 520, remote access controller 525 may provide redundant identification of some hardware components and may provide exclusive identification of other hardware components, such as internal memories, management controllers or logic units utilized by the remote access controller 525. Also as with TPM 520, in some embodiments, the inventory certificate validation process 510 may compare identity information for the detected remote access controller 525 against the remote access controller identity information that is parsed from the inventory certificate at block 545. In some instances, the detection of any discrepancies between the identity of the remote access controller specified in inventory certificate and the identity reported by remote access controller 525 may also result in terminating any further validation procedures.

At block 650 and as indicated at 565, the inventory certificate validation process 510 may retrieve any additional inventory information from any other data sources, such as directly from the processor of the IHS or from a chassis management controller of a chassis in which the IHS has been installed. Upon collecting the detected hardware components of the initialized IHS, at block 570, the inventory validation process 510 compares the collected inventory information against the inventory information that is parsed from the signed inventory certificate, and in particular against the signed inventory of factory-installed hardware of the IHS. However, prior to validating the detected hardware, at block 655, the inventory certificate validation process may first confirm the identity of the detected TPM against the identity of the TPM reported in the signed inventory certificate. If the identity of the TPM is successfully validated, validation may continue at block 660. However, if the identity of the TPM is not validated, at block 680, the inventory certificate validation process may signal an inventory validation failure since any discrepancies between the identity of the factory-installed TPM and the TPM that has been detected in the initialized IHS signals a potential compromise in the root of trusted hardware components of the IHS.

At block 660, the inventory certificate validation process may confirm the identity of the detected remote access controller against the identity of the remote access controller reported in the signed inventory certificate. If the remote access controller is successfully validated, validation may continue at block 665. Otherwise, if the identity of the remote access controller is not validated, at block 680, the inventory certificate validation process may signal an inventory validation failure. As with the TPM, any discrepancies between the identity of the factory-installed remote access controller and the remote access controller detected in the initialized IHS signals a potential compromise of the root of trust of the IHS.

At block 665, the inventory certificate validation process continues the comparison of the detected hardware components of the initialized IHS against the identities of the hardware components that are included in the signed inventory certificate, and in particular against the signed inventory of the factory installed hardware components that is included in the signed inventory certificate. In implementing this comparison, the validation process 510 may generate a digital signature based on the collected hardware inventory data, in some cases using cryptographic operations supported by the remote access controller 525 or by another trusted component of the IHS. If the digital signature calculated from the inventory of detected components matches the signed hardware inventory from the certificate, the validation process 510 has successfully confirmed that the IHS includes only factory-installed hardware, with none of the factory-installed hardware missing and no detection of any unidentified hardware. The customer receiving delivery of the IHS is thus assured that the IHS is operating using only the factory-installed hardware components, including lockable devices, specified in the inventory certificate.

If any lockable storage devices, or hardware devices of any type, are detected that are not identified the inventory of factory-installed hardware, at block 680, the inventory certificate validation process may signal an inventory validation failure. In some embodiments, an inventory validation failure will also be signaled if the validation process identifies factory-installed lockable storage devices, or other hardware, specified in the inventory certificate that is not detected as a component of the IHS, such that successful validation requires confirming that an IHS is operating using all of the factory-provisioned lockable storage devices, but no additional lockable storage devices.

Upon successfully validating the hardware in use by the IHS, embodiments may continue, at 667, with the further validation of the lockable storage devices, and in particular with the validation that the customer is able to recover the encrypted code required to unlock the storage devices. As indicated in FIG. 5 , at 572, the cryptographic keypair of the customer that has been used to encrypt the access code for the storage device is identified. In some embodiments, a validation process operating on an IHS, such as operating on the remote access controller 525 or another trusted component, may be configured to invoke use of the customer’s cryptographic keypairs to decipher access codes for lockable storage devices. In such embodiments, at 574, the validation process may use the customer’s cryptographic keys to decipher the encrypted access codes, thus allowing the validation process to confirm whether the recovered access codes do indeed provide access to the lockable storage device. In other embodiments, the validation process may provide the encrypted access codes for lockable storage devices to an external service operated by the customer, where this external service utilizes the customer’s private keys to decipher the encrypted access codes from the inventory certificate. In such instances, the external service may provide the decrypted access code to the validation process for confirmation, at 574, that a lockable storage device is operable using the deciphered access code.

If the detected lockable storage devices match the factory-installed lockable storage devices and if the encrypted access codes are successfully deciphered by the customer’s private key to confirm access to the lockable storage devices, at block 680, the inventory certificate validation process signals a successful validation of the detected hardware of the IHS, including validation that the IHS has access to one or more lockable storage devices installed in the IHS. The customer receiving delivery of the IHS is thus assured that the IHS is operating using only lockable storage devices that were installed at the factory during manufacture of the IHS. More particularly, embodiments provide validation an IHS includes one or more specific factory-installed lockable storage devices and does not include any other lockable storage devices, thus providing assurances to a customer receiving delivery that the IHS includes only factory installed and provisioned hardware.

Embodiments may also serve to bind a lockable storage device to a particular IHS, such that the lockable storage device cannot be utilized on any other IHS. As described, in some embodiments, the access code for a lockable storage device may be generated during factory provisioning by the remote access controller of the IHS. As described with regard to FIG. 1 , a remote access controller may include cryptographic capabilities by which keypairs may be generated, including the keypair used to sign the inventory information included in the inventory certificate. Since only the remote access controller has access to this particular private key, the inventory certificate is thus anchored or bound to the IHS such that no other IHS is able to decipher encoded information included in the inventory certificate. In this same manner, a customer may bind a lockable storage device to a particular IHS such that the lockable storage device is not operable on any other IHS. For instance, in embodiments where the remote access controller, or another trusted component of the IHS, is assigned use of the customer’s cryptographic keypair used to decipher encrypted access codes for lockable storage devices, such access codes are thus bound to that IHS since the access codes can only be recovered from the encrypted access codes in the inventory certificate by this trusted component of the IHS.

FIGS. 5 and 6 describe embodiments for use of an inventory certificate in the validation of an IHS as including only genuine lockable components, such as lockable storage drives, where the inventory certificate may be an original inventory certificate generated during factory provisioning of the IHS, or may be an updated inventory certificate that has been generated by a trusted validation service, such as in response to modifications to the hardware components of an IHS. FIG. 7 describes the generation of an updated inventory certificate by a remote validation service in response to a lockable device, such as a lockable storage device, being added or removed from an IHS by a customer.

FIG. 7 is a swim lane diagram illustrating responsibilities of components of a system configured according to certain embodiments for updating the lockable storage devices that may operate on an IHS. As described, factory provisioning of an IHS according to embodiments generates a signed inventory certificate that specifies the factory-installed hardware components of the IHS, including lockable storage drives or other lockable components. An inventory certificate is signed by a factory certificate authority and stored on the IHS. In some embodiments, the factory provisioning application stores a copy of the signed inventory certificate for later use, such as use by the remote validation service 720 in supporting modifications to the IHS at a later time. Once the factory provisioning of the IHS has been completed, the IHS is packaged and shipped to a customer. As described with regard to FIGS. 5 and 6 , upon receiving shipment of the IHS, the customer may validate that the IHS includes only factory-installed lockable storage devise and confirms the customer controls the private key that correctly deciphers the access code in the inventory certificate.

Operation of the IHS may proceed with use of only the factory-installed lockable storage devices until modifications to the available lockable storage devices are deemed necessary. For instance, a customer may repurpose and/or relocate an IHS in a manner such that a lockable drive is no longer needed and is being removed from the IHS, or an IHS may be repurposed and/or relocated such that a lockable storage drive is being added to the IHS. In instances where the lockable storage devices of an IHS will be modified, at 725, a trusted entity 705 may notify the remote validation service 720 of the change. As indicated in FIG. 7 , the validation service 715 may receive notification that a lockable storage device is being removed from an IHS, or that a lockable storage drive is otherwise being disabled. When a storage device is being added, the trusted entity 705 may provide the validation service 720 with the identity of the added lockable storage drive and an encrypted access code for the lockable storage device that is being added. In various embodiments, a trusted entity 705 providing an update to the lockable storage devices of an IHS may include the manufacturer of the IHS, the customer, a retailer that sells parts on behalf of the manufacturer, or by a trusted third party providing ongoing support of the IHS.

In response to a trusted entity 705 providing modifications to the lockable storage devices of the IHS, at 730, the remote validation service 720 retrieves the copy of the existing inventory certificate for the IHS, such as from a repository maintained by the manufacturer of the IHS. At 735, the remote validation service 720 generates a new signed inventory certificate that specifies the updated set lockable storage devices that may operate on the IHS and the encrypted access codes for each of these lockable storage devices. In some embodiments, the updated inventory certificate that is generated by the remote validation service 720 may be signed by a factory certificate authority that utilizes a hardware security module, such as described with regard to FIGS. 3 and 4 . In some embodiments, the new signed inventory certificate may be signed by a different certificate authority that is utilized by the manufacturer of the IHS or by a trusted entity that is providing ongoing support of IHS.

At block 740, the remote validation service 720 transmits the updated inventory certificate to the IHS, where the updated certificate may be validated and then stored by the remote access controller, as described above, such that it replaces or augments the prior inventory certificate. Upon detecting the receipt of an updated inventory certificate, at 745 of FIG. 7 , the validation process 715 may retrieve the updated inventory certificate and confirm the updated certificate corresponds to the root of trust of the IHS. As provided above, an inventory certificate may specify identity information for hardware components that operate within the root of trust of an IHS, such as a remote access controller and a TPM. When lockable storage devices are being added or removed from an IHS, such changes do not affect the cryptographic binding of an inventory certificate to the IHS. Accordingly, the root of trust of an IHS should not affected by adding or removing lockable storage devices. The validation process 715 may thus confirm that the updated inventory certificate is bound to the root of trust of the IHS before evaluating the updated set of lockable storage devices included in the updated certificate. If the updated certificate is confirmed as bound to the root of trust of the IHS, validation process 715 may also validate the integrity of the updated inventory information included in the updated inventory certificate.

The validation process 715 may then initiate procedures for comparing the detected hardware inventory of the IHS, including the detected lockable storage devices, against the inventory reported in the updated inventory certificate, including the factory-provisioned lockable storage devices. As described above, such inventory validations may be conducted by the validation process 715 in a pre-boot environment or diagnostic environment during which the operating system of the IHS is not operational. As such, evaluation of an updated inventory certificate may trigger re-booting of an IHS in order to initialize such pre-boot or diagnostic environments. Operating within such a pre-boot environment, at 750, the validation process 715 retrieves an inventory of the detected hardware components of the IHS, including the detected lockable storage devices, as described with regard to FIGS. 5 and 6 . At 755, the validation process 715 determines whether the detected hardware inventory of the IHS matches the inventory reported in the updated inventory certificate, and in particular, whether the detected lockable storage devices match the factory-provisioned lockable storage devices specified in the updated certificate. As above, at 760, the encrypted codes in the updated inventory certificate are deciphered using a private key of the customer such that the deciphered access code may be used to validate that the code does indeed provide access to a lockable storage device that has been added to the IHS.

If no discrepancies are identified with regard to the lockable storage devices and the encrypted access codes specified in the inventory certificate can be deciphered using a private key of the customer, the customer may be assured that the IHS is operating using only factory-provisioned lockable storage devices. However, if a lockable storage device is detected that is not identified in the inventory of factory-provisioned lockable storage devices from the updated inventory certificate, the validation process 715 may suspend further operations and may signal a validation failure.
